During operation of a nuclear power plant the neutron radiation of the reactor core may induce activity in surrounding components and equipment. These may in turn become radiation hazards during decommissioning or component exchanges. To better plan for this, models of the degree of activation and subsequently, the dose are therefore of great importance. Building upon a previous study of the neutr
The law concerning visitation zones has been widely debated in Sweden. While some see it as a necessary measure to fight the continuous gang violence, others are concerned it will create a divide between the police and the people in the areas they are put up. These presumed areas for the visitation zones are areas of low socio-economic status and with a high crime rate. Therefore, the purpose of t
I takt med att hjärt- kärlsjukdomar ökar har även diagnostiseringstekniken av dessa sjukdomar blivit bättre. Coronar Percutan Intervention (PCI) är en invasiv dignostiskmetod som ökat de senaste åren. Sjuksköterskans roll har ökat i samband med omhändertagandet av patienter efter PCI, t ex. introducerdragning, smärtlindring och att förhindra uppkomst av blödningskomplikationer. Syftet med denna li
AbstraktInledning: Vid datortomografi av huvudregionen måste hänsyn tas till strålningskänsliga organ t.ex. ögonlinsen och thyroidea. Minimering av patientstråldoserna med bibehållen bildkvalitet är en viktig omvårdnadsåtgärd för röntgensjuksköterskan.Syfte: Syftet med studien var att genom fantommätning bestämma den stråldos en patient får som genomgår datortomografi standard CT singleslice- och
The dominance of men in politics has been a long standing trend, with women historically underrepresented in this sphere. Efforts toward women's inclusion in politics seek to address and rectify this gender imbalance, advocating for greater representation, equal opportunities, and the dismantling of barriers that have hindered women's active participation in political decision-making proce
As the world is trying to rid itself of its dependence on fossil fuels, the need for renewable energy is rapidly increasing. In the power distribution network (DN), this takes the form of distributed generation (DG) from renewable sources, such as photovoltaic (PV) power production. But as more DG is installed, it can lead to issues in the DN such as overloading and overvoltage when production is
Energy efficiency in buildings can be understood elaborately by evaluating its operational and embodied energy. Embodied energy is the sum of all the energy that is used to produce materials in a building construction. This study assesses various building parameters e.g. U-value of the materials, Window to Floor Area Ratio (WFR), location, etc. that affect the operational and embodied energy and u
This report summarizes the advantages and disadvantages of organic and conventional farming from an environmental and sustainable perspective. A sustainable agriculture system needs to be able to meet a higher demand for food due to a growing population and minimize the damage of the environment at the same time. The main critic to the organic farming system is that it produces lower yields than
Large district heating networks often have a complex structure that requires iterative calculations to determine the flow distribution throughout the network. This Master’s thesis describes a piece of software implementing methods and data structures to determine and present the flow distribution and pressure state in such district heating networks. The purpose of the thesis work was to create a t
Until today, little research has been made of how individuals develope emotional relations to their clothes. Women have been, and still are, the main focus in most of the contemporary studies, therefore it exists a lack of knowledge of how men and women can relate differently to their clothing. The primary aim of this study is to illustrate how young men and womens different approaches to fashion,
In this master thesis, combinations of noise-canceling LNA and harmonic-rejection mixers are investigated and compared to find an optimal inductorless receiver front-end for low-band (600-960MHz) FDD LTE-A network. The work was carried out in a modem development project at Ericsson Modems, Lund. Three receiver versions with different harmonic rejection techniques are compared in terms of noise fig
Negative symptoms in schizophrenia spectrum are associated with minimal treatment responses. The search for effective treatments is potentially hampered by heterogenous study-designs and sample characteristics depending on the intervention category. This PRISMA-compliant systematic review/synthesis aims to describe the literature on negative symptoms interventions for schizophrenia spectrum disord
To make surgery more precise and to shorten anesthesia-times for children undergoing surgery for Hirschsprung’s disease, ultra-high frequency ultrasound (UHFUS) has been suggested to replace peroperative biopsy. The study’s aim was to determine quantitatively whether aganglionic and ganglionic bowel segments could be distinguished by UHFUS. Bowel specimens of 23 children operated on for rectosigmo
Resin adsorption is an effective technology for the fermentable sugar slurry detoxification in lignocellulosic biorefinery, but with the great limitation of the loss of resin capacity from inhibitor contamination and the extensive use of acid and base solutions for their regeneration. In this study, we developed a green and practical method with ultrasound assisting the depletion of poisoned resin
While many studies have examined carbon dynamics of boreal ecosystems following wildfire, research on forest-atmosphere carbon fluxes during widespread smoke events from adjacent active wildfires is limited. We examined eddy covariance carbon exchange adjacent to the May 2011 Utikuma Complex wildfire in central Alberta, Canada. Over a one-week period while the wildfire was burning <10 km from the
